[LAU] multitrack export midi type 0 (gramophone2) issue

[Benoît Rouits]

Hello,

I have written generative composition with a chomsky grammar parsed by 
and *old* program called gramophone2. Unfortunately, my tests 
composition have multitrack but gramophone2 generates midi type 0 files 
(1 merged track).

So, all midi sequencers i tried does only import track #1 while there 
are 3 or 4 in the midi file with different speeds (i'm playing with yet 
another phasing music). It may be a grammophone2 bug, but before to dive 
into the code (if i find it) how could i convert the generated midi type 
0 into a type 1 so that tracks speeds can be aligned ?

With the hope the question is well asked and not out of topic.
